Cartilage is a type of dense connective tissue. It is composed of cells called chondrocytes which are dispersed in a firm gel-like ground substance, called the matrix. Cartilage is avascular (contains no blood vessels) and nutrients are diffused through the matrix. Cartilage is found in the joints, the rib cage, the ear, the nose, in the throat and between intervertebral disks. There are three main types of cartilage: hyaline, elastic and fibrocartilage. The main purpose of cartilage is to provide a framework upon which bone deposition could begin. Another important purpose of cartilage is to provide smooth surfaces for the movement of articulating bones.
Composition
Much like other connective tissue, cartilage is composed of cells, fibers and a matrix.
Cells
Chondrocytes and the precusor forms of chondrocytes known as chondroblasts are the only cells found in cartilage. Chondrocytes make up "cell nests," groups of chondrocytes within lacunae. Chondroblasts are responsible for the secretion and maintenance of the matrix. Chondroblasts encased in matrix develop into chondrocytes. The matrix immediately surrounding the chondrocytes is referred to as the territorial matrix and stains darker than the interstitial matrix. Chondrocytes lie in a cavity called a lacuna. During slide preparations, chondrocytes often shrink and appear smaller than the lacunae but in live tissue, they occupy the entire area. More on [ Cartilage ]
